This video shows George Osborne was right when he called a journalist a 'revolutionary Marxist'

Chancellor George Osborne has called former BBC Newsnight and
Channel 4 economics editor Paul Mason a "revolutionary Marxist
broadcaster". Speaking in the House of Commons on Tuesday,
Osborne mocked the fact that Labour's Shadow Chancellor John
McDonnell has signed up Mason and former Greek finance minister
Yanis Varoufakis to speak at his ‘New Economics’ lecture
series.

"The fact that the Labour Party is now getting its advice from
Yanis Varoufakis and the revolutionary Marxist broadcaster Paul
Mason does not suggest to me that they’ve got an answer to
economic security. Presumably they chose those two because
Chairman Mao was dead and Mickey Mouse was busy," Osborne said.

It might sound extraordinary for the Chancellor of the
Exchequer to accuse a journalist of being a Marxist, but Osborne
isn't wrong. This is what
Mason told the Independent in 2015:

"I am quite happy to call myself a Marxist at the level of method
... because historical materialism as a method is a great tool
for understanding history."

In addition, Business Insider has unearthed this video of Mason
handing out "Workers Power" newspapers outside the Chesterfield
Socialist Conference in 1987. Workers Power is
a revolutionary Trotskyist organisation that Mason describes
in the video as a "tendency within the Labour Party" — in
other words, an entryist organisation.

Mason later wrote a post on Medium detailing his beliefs: "It
is completely inaccurate," he wrote. "I am radical social
democrat who favours the creation of a peer-to-peer sector
(co-ops, open source etc) alongside the market and the state, as
part of a long transition to a post-capitalist economy."
